Chelsea manager Jose Mourinho refused to be drawn too much on his opinion of the suspension handed to Blues striker Diego Costa.

Costa was slapped with as three-match ban after being found guilty of violent conduct towards Arsenal defender Laurent Koscielny during Chelsea's 2-0 win over Arsenal on Saturday.

Mourinho indicated that he refused to comment when asked about his view of the incident, in which Costa appeared to strike Koscielny in the face with a flailing hand, but clearly revealed more than he had initially planned to.

"If I bring examples, if I go deep and if I bring feelings into the discussion a big suspension will be waiting for me and I don't want that," Mourinho told Sky Sports.

"The team doesn't need that, the team lost an important player for three matches and I don't think they need to lose their manager.

"Every time you lose a player it's not good for the team. It's easier to accept an injury but this kind of situation goes much more deeper in feelings and the team is hurt.

"But now we know something, that retaliation is allowed now. No problem, you can do it."
